NON-REFILLABLE BOTTLE.

Specification of Letters Patent. Patented Oct 13, 1914.

Application filed May 10, 1913. Serial No..766,780.

To all whom it may concern:

Be it known that I, BENJAMIN F. KLASS, a citizen of the United States,and a resident of the city of New York, boroughlof Bronx, in the countyand State of New York, have invented a new and Improved Non-RefillableBottle, of which the following is a full, clear, and exact description.I

. This invention relates to an improved nonrefillable bottle, that is, abottle or vessel which, after its contents have been dispensed, cannotbe refilled without destroying the bottle, thus serving as an effectivemeans for preventing the sale of liquids or the like unscrupulously.

The invention resides in the provision of a very simple combination ofcooperating parts requiring but slight change in the construction of thebottle to provide for the mounting of a float valve permitting theescape of the liquid or fluid but preventing refilling of the bottle,the parts being constructed of glass or similar vitreous material withthe exception of the holding means for a combined bafiie wall andbearing disk for the valve.

1th the above and otherobjects in view, the invention resides moreparticularly in the peculiar combination and arrangement of parts whichwill be illustrated as a preferred embodiment in the accompanyingdrawings and described'in the specification.

Reference is to be had to the accompanythrough a fragmentary portion'ofa bottle and parts mounted in the neck thereof to prevent the refillingof the bottle in accordance with the invention; Fig. 2 is a sectionalview similar to Fig. l but showing the bottle tipped and with the valvein an open position; and Fig. 3 is a plan view of the combined bathewall and bearing disk, the same being partly broken away.

In the drawings, the numeral 5 designates the body of the bottle whichis of glass or other vitreous material in its preferred embodiment, andwhich is provided with a neck portion 6 ordinarily closed by a cork orother closure 7. In accordance with the present invention, the interiorof the neck is slightly tapered to provide a ground fit as ,tion 8thereof is shown at8, and the interior face. of the neck atthe junctureof thelatter with the body is provided with an interior projection ofbeveled form producingafvalveseat 9. Fitted in the neck and conformingto the pora combined baflie wall and bearing disk 10 which is also ofglass or similar vitreous-material, and which is preferably in. the formof a pair of upper and lowersectionsyll and 12,,spaced apart but formedin one through the instru'mentality. of a plurality of. connectingstrips or sections 13. spaced apart at the peripheral edge of the disk.Two of these'strips, diametrically opposed, areprovided with verticalrecesses 14 and normally outwardly curved leaf springs 15 have their;,lower ends em- I bedded in the lower sections 12 of the disk so thattheir upper ends will normally project outwardly of the peripheral edgethereof. The purpose of this is to hold the diskin the neck of thebottle, and for this, purpose the neck at dimetrically opposed pointsinteriorly is provided with notches 16 having their upper walls locatedat right angles to the length of the neck and their side walls taperingin width downwardly so that when the diskis placedinthe neck the springswill move into the recesses 14. until they are I )ermitted to expandinto the notches 16 and by engagement of their extremities withthe.

upper wallsof the recesses, prevent the removal of the disk. t

A Valve 17 in the form of a hollow float adapted, when submergedin thefluid which the bottle is designed to contain, to a point vindicated bytheline in Fig.1,

has a tapered lower portion 18' of truncated form to cooperate with theseat 9 and normally close the neck of the bottle. The weight of thevalve. and its upwardly extending stem 19 will depend upon the specificgravity of the fluid or liquid which the bottle is adapted to contain,and this stem passesthrough and is guided in a central opening 20 inthelower disk section12 and a socket 21 communicating only with thelower face of the upper disk section 11, the upper end of the valve stembeing movable in this socket, whereby it may be moved to the openposition indicated in Fig. 2 of the drawings.

The disk sections are provided with vertical passages or openingstherethrough, the passages 22 in the disk 11 being spaced apart andpreferably located nearer the center of the disk than the passages 23through the lower section, so that the openings or passages in therespective sections of the disk are located in staggered relation toprevent the entrance of an instrument for holding theva-lve 17 openshould an attempt be made to uns'erupulously refill the bottle. To

' further prevent this, the passages terminate the" latter is shovedinto the bottle neck and held by the springs as described. When it isdesired to pourv the contents of the bottle the liquid win elevate thefloat valve sufficiently to unseat. it and permit the passage of-the'liquid, and the same will pass through the staggered passages andthrough the sections of the disk, but inasmuch as the liquid willbeno'i'mally disposed below the valve, the latter wi l return by gravityto a closed position and seal the contents. It is ofcourseundersjtoodthat the cork 7 is reinoved when it is desired-to pourthe contents of the bottle. On the other hand, should an attempt be madeto refill the bottle the pressure of the liquid on the top of the valvewill hold it closed and the staggered relation ofthe openings, togetherwith the extensions provided, will prevent the openingofthe valve fromthe exterior. Furthermore, should it be attempted to fill the bottle byimmersion, the liquid will pass through the passages, but in strikingthe 1 valve the latter, by its floating action, will at once beeseatedto close the bottle neck and prevent the entrance of the liquid into thebottle. A Very weak coil spring 26 is mounted in the socket 21 to act onthe stem 19 toassist in the seating of the valve, but not to prevent thevalve from unseating under the pressure of the liquid when pouring thelatter. The spring is not exposed to the liquid and therefore cannotcontaminate the same.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A non-refillable bottle having a neckportion provided with an interior seat, a float valve having a stem,said bottle and valve being constructed of vitreous material, means toseat the valve, and a disk held in the neck against outward displacementand slidably receiving the stem of the valve for limited upward movementin unseating, said valve-seating means being carried by the disk, thedisk embodying spaced upper and lower sections, said sections havingpassages therethrough located in staggered relation and terminating withextensions extending into the space between the sections.

2. A non-refillable bottle having a neck portion provided with a seat, afloat valve having a reduced solid stem, means to seat the valve, and adisk held in the neck against outward displacement. and slidablyreceiving the stem of the valve, said valveseating means acting on theupper end of the stem and being inclosed by the disk, the disk having aninterior opening providing upper and lower portions having passagestherethrough, said passages terminating in extensions located within thearea of the openings.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
